Abstract

A stretched multilayered film comprising at least eleven layers which consist of layers of one kind stacked alternately with layers of the other kind and each has a thickness of 0.05 to 0.3 νm, wherein the layers of the first kind are made of a polyester comprising polyethylene 2,6-naphthalenedicarboxylate as the main units, the layers of the second kind are made of a thermoplastic resin having a lower refractive index than the polyester, and at least either of the layers of the first kind and the layers of the second kind are layers which differ in thickness and in which the value obtained by dividing the thickness of the thickest layer by that of the thinnest layer is 1.2 or larger. This film reflects selectively in a widely range a light having a desired wavelength region. It is hence useful as a near-infrared-ray reflection film for plasma display front panels.
